Ween you klick on the Kmail icon for the first time after startup, a seperate instance of Kmail is opened instead of the inline part. Klicking on a folder in summary view works fine. After that the button seems to work fine until kontact is closed. Christian
This works fine for me with a recent CVS-compile. Can you try with KDE 3.2RC1?
I will if I find the time to compile it. As I do not have any real trouble with the beta2 I planned to wait for the release and not install the release candidats.
This bug is gone in kde 3.2.0
